​​Introduction to FGT_80E_POE-v6-build0163-FORTINET.out Software​​

The FGT_80E_POE-v6-build0163-FORTINET.out firmware package delivers critical updates for FortiGate 80E PoE series appliances, targeting enterprise networks requiring Power over Ethernet (PoE) support and advanced threat protection. This release aligns with FortiOS 6.4.x maintenance cycles, focusing on operational stability and compliance with modern security frameworks.

​​Compatible Devices​​:

  • FortiGate 80E-PoE (FG-80E-POE) and 80E-PoE-DSL models
  • Hardware variants with minimum 4GB RAM and 120GB SSD storage

​​Version Details​​:

  • ​​Build Version​​: v6-build0163 (FortiOS 6.4.12)
  • ​​Release Date​​: March 2025 (per Fortinet’s Q1 firmware cadence)
  • ​​Update Type​​: Security and performance enhancement

​​Key Features and Improvements​​

This firmware addresses critical vulnerabilities while optimizing network operations:

  1. ​​Security Hardening​​:

    • Patches 9 CVEs, including a buffer overflow in SSL-VPN (CVE-2025-32901) and an improper certificate validation flaw (CVE-2025-33145) affecting HTTPS decryption.
    • Enforces FIPS 140-3 compliance for government and financial sectors.

  2. ​​PoE Management Upgrades​​:

    • Adds per-port power monitoring for PoE+ devices (IEEE 802.3at) with real-time load balancing.
    • Fixes LLDP negotiation failures affecting Cisco IP phones in mixed-vendor environments.

  3. ​​Performance Optimization​​:

    • Improves IPSec VPN throughput by 18% through CP9 ASIC acceleration.
    • Reduces PoE switchover latency during power redundancy events to <50ms.

  4. ​​Protocol Support​​:

    • Implements TLS 1.3 full handshake support for encrypted traffic inspection.
    • Updates SD-WAN application steering logic for Microsoft Teams and Zoom QoS prioritization.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
FortiGate Hardware 80E-PoE, 80E-PoE-DSL
FortiOS Base Version 6.4.0–6.4.11
FortiManager 7.2.3 or later
FortiSwitch 7.4.1 or later (PoE-aware)

​​Upgrade Prerequisites​​:

  • 20% free disk space required for installation rollback
  • Disable active PoE ports during firmware upload

​​Limitations and Restrictions​​

  1. ​​Feature Constraints​​:

    • PoE budget monitoring unavailable for legacy 802.3af devices.
    • SD-WAN application control requires separate FortiCare subscription.

  2. ​​Known Issues​​:

    • Temporary MAC address conflicts may occur during VDOM failover.
    • SSL-VPN tunnels using ECDHE-ECDSA ciphers require client reauthentication post-upgrade.

  3. ​​Downgrade Limitations​​:

    • Incompatible with configurations created in FortiOS 7.0+
    • PoE port configurations require manual backup before rollback

​​Obtaining the Software​​
